You can't change it via settings, I can't change it either. What did you want to change it to? I'll point someone who can here when you've answered, You haven't recorded anything so I don't need to tell you it will not change anything that's already out on the net
And the advice you were given last year still applies viewtopic.php?f=23&t=70452&p=1471579#p1471579

It's much easier to not change the forum name, since it requires a "super-admin" with special powers to do it. Please only request this if you really REALLY, want/need it changed. If it's an "I'd rather have my forum name as "funkyryfink" simply because I like it better", then please don't request it.)

The catalog name is easy for any admin to change. It will not affect what name shows in the MW (that's your forum name) but it will change the name showing on catalog pages, when projects are complete.
